Hi and thanks for the question today.
Chlamydia and Gonohrrea is what's called a 'send out' lab at our office. I work in Urgent care and we send these out to a lab called LabCorp. It takes us 2 days to get results back. Bacterial Vaginosis is done via wet prep in house and can results back within about 5 minutes. Other labs like HIV and Hep will have to be a send out as well. These usually takes 2-3 days as well. OB/GYN office may have their own labs which means they can get things done quicker, but most will send out test like Chlamydia.
Syphillis is a send out also. This one is almost ALWAYS a send out. This one takes 2-3 days to come back as well.
